There is increasing evidence that microstructures play an important role in the maintenance of multipotency stem cells. However, it not clear how micropatterns affect stemness We prepared different sizes, shapes and aspect ratios used them for culture mesenchymal cells (MSCs) derived from human bone marrow to investigate their influence on MSCs at single cell level. The percentage positively stained by markers decreased with spreading area ratio. cellular geometry controlled geometrical had...
Abstract Adhesion and spreading are essential processes of anchorage dependent cells involved in regulation cell functions. Cells interact with their extracellular matrix (ECM) resulting different degree adhesion spreading. However, it is not clear whether or more important for In this study, 10 types isotropical micropatterns that were composed 2 μm microdots prepared to precisely control the area human mesenchymal stem (MSCs). The respective influence areas on functions was investigated....
One of an essential characteristic human skin are time dependent mechanical properties. Here, we demonstrate that stiffness dermal fibroblast correlates with age and it can be restored after anti-wrinkle tripeptide treatment. The fibroblasts isolated from donors 30-, 40- 60 years old were examined. Additionally the effect anti- wrinkle latter cells was investigated. atomic force microscopy measurements performed on untreated as well treated peptide. Young's modulus for two indentation depths...
Atomic force microscopy (AFM) and fluorescence was applied to determine the influence of anti-aging peptides on morphology mechanical properties keratinocytes. Immortalized human keratinocytes (HaCaT) were treated with two bioactive peptides: Acetyl Tetrapeptide-2 Hexapeptide-50 (Lipotec). The AFM measurement keratinocyte stiffness carried after 48 h exposure at an indentation depth 200 nm. analysis showed increase cell for cells (P1) in concentration range. (P2) 0.05 µg/ml also increased...
Magnesium alloys are essential materials for aircraft applications however their corrosion protection is still a challenge and restriction from the spread of applications. Owing to there need search new way protect magnesium in replacement currently used chromate coatings which manufacturing process dangerous harmful living organism will be soon forbidden by law restrictions. In this work, novel surface modification alloy AZ91E was realized. A hybrid coating made combining oxide Diamond-Like...
With a range of biological properties, single-walled carbon nanotubes (SWCNTs) are promising material for nanobiotechnology. Concerns about their potential effect on human health have led to the interest in understanding interaction between SWCNTs and cells. There many reports showing cellular effects but this issue is quite controversially discussed literature. In study, we used conventional evaluation methods atomic force microscopy (AFM) compare three different cell types: bovine...
Atomic force microscopy (AFM) was used to explore the cellular effects caused by magnetic nanoparticles.
It is important to elucidate the effects of carbon nanotubes on cell functions for their biomedical applications. In this study, effect single-walled (SWCNTs) mechanical property chondrocytes was investigated by atomic force microscopy. Chondrocytes were cultured in medium containing SWCNTs and showed an increase uptake with culture time. The or without measured at indentation depth 200 nm 500 nm. higher Young's modulus than that cells both depths. became significant after more 3 hours....
This article presents the results of experiments, which examine cell mechanisms with goal confirming effective action active ingredients used in anti-aging cosmetics. Skin stiffness measurements use an atomic force microscope on two forms vitamin C (ascorbyl tetraisopalmitate and l-ascorbic acid) have been presented. The estimated Young's modulus for three types cells (a control as well treated C) has shown significant differences tested was confirmed histological staining experiment....
